SHA256 hash the body and base64 encode in Python Vs TypeScript

My goal is to hash the body in SHA256 and then encode it with base64. I am converting python code to TypeScript.

Based on google search, what I understood is, crypto can be used against hashlib and base64. Here challenge is, when I use .createHmac then it requires the secret when in python I can directly work with body. Is it another way to achieve python result in typeScript?

NOTE: This is the first time I am seeing python code so please correct me if I am missing something here.

Python Code:

import hashlib import base64 body = "johnDoe" abc = base64.b64encode(hashlib.sha256(body.encode('utf-8')).digest()) print(abc) 

Output:

b'RnuqbBqTNwQ7v3g3tKsVAi+NUALBCUeoRBEq6Yil6RA='

TypeScript Code: Using createHmac

var crypto = require('crypto'); var secret = "PYPd1Hv4J6"; var body = "johnDoe"; var hmac = crypto.createHmac("sha256",secret); var hmac_result = hmac.update(body).digest('base64'); console.log(hmac_result); 

Output:
